A licants filed Apri1 29,

I Thisinvention relates to an improved tool for removing dents from metal bodiesyandit has more particular reference to an appliance of this classification which is expressly, but

not necessarily, adapted for use in servicing garages and analogous repair StiltlOIlStO enable theuser to straighten, smooth and sub-' 'stantially remove dents from metal bodies and fenders ofautomobile's so as to permit restoration of the repairedpart to its original of additional agents or accessories which are molded form. 1

The tool is so designed plied to-any type or design of fender andto that end the tool is adjustable and rev rsible j and permits actionin almost every'possible direction. It is so designed that the fender need not be removed from the car. The power required is human or hand power and requires no application of outside power, sim Q, ply used by the hands ofthe operator-and with human or body strength.

The tool is serviceable and used. by the application of force and pressure developed by screwing the steel rod and in this manner g; bringing the rollers into place where, re-

--quired onthe damaged fender or indented body or fender and after the toolhas beenthus adjusted, by movement and manipulation by the operator, the rollers are so applied as to originally molded or pressed and restoring the same to its original form and mold. Pressure may be readily applied or released as the operator may desire and large'or' and as the size of the dent or damage tothe fender may require.

Another feature and advantage of the de-q vice is thatit is susceptible of being employed,

expeditiously and in a feasible manner by either skilled or unskilled hands, to restore fenders and body dents in a scientific andusa ble manner, and to provide a tool that is at:

once usable, serviceable, vand characterized by exceptional simplicity in construction and adaptability.

constructedin accordance with'the presenti n yention.

iguresB and a are cross sectional views taken on the lines 3'3 and ll of Figure 1.

Figure 5 is a view of the lower end portions Y of the comp anion jaws showing a pair of complemental work-engaging accessories.

i1 igures b and *4 are detail elevatlonal views interchangeable in an obvious manner.

Inthe drawings in Figure l the frame is v 7 generally designated by the referencechar acter 8 and this comprises a pair of symmetrical companion bar members or sections 9 and 10 of general L-shap'ed configuration. The inturned short arms are coupled together through the medium of a coupler 11 at the top. This coupler is centrally apertured to provide a "guide for'passage of-the smooth stem poreach of which includes a right-angularly disv posed collar 18functioning as'a socket for' reception of the stem 19 of the complemental; appliance or accessory generally designated by the numeral20. Theaccessorycomprises a stem 19 and a substantially U-shaped yoke 21, whose arms are formed with bearing holes to accommodatethe ends of'the pin 22 on which the surfacing and pressing roller '23 .is mounted for'rotation. V

These devices are used in opposed pairs. There are other interchangeable accessories also employed. For example, as seen in Fig ure 5-,the numeralM'desi'gnatesa substantially semi-circular tire grip designed to partly embrace a conventional automobile tire and havinga stem portion 25 and a pivotal c'onneetion26; It will be noted that in each instance a: set screw 27 is rovided for holdin P o the stem in place. I might mention also that substitute rollers areprovided. "For instance,

the rolle'r 28 in Figure 6 or the roller29 in Figure 7 may be substituted for the truly cylindrical type of roller 23 already described.

Any number of suitable attachments will of course be provided to accommodate the particular character of metal work being reconditioned.

The numerals 30 designate sleeves slidably adjustable on the arm portion of the parts 9 and 10 these sleeves being held in set position by the set screws 31. Duplex toggle connections are provided between screw threaded portions 14 and 15 and the sleeves. Each toggle comprises suitably connected and arranged operating links 32 pivotally connected at their outer ends with the respective sleeves and pivotally connected at their inner ends with the feed blocks 83 adjustably arranged on the opposite screw threaded portions 14 respectively. This arrangement provides the desired expansion and contraction of the parts 9 and 10 through the medium or the toggles and adjustable sleeves.

Thus the attachments on the ends of the jaws may be properly engaged with the fender or other work being re-shaped or repaired.

It is evident from the foregoing description and drawings that I have evolved and produced a novel rolling and bending tool for metal work which is especially designed for reconditioning automobile fenders and the like.

The gist of the invention is in the provision of a suitable arrangement of jaw sup porting members coupled together in appropriate pivotal relationship and so shaped and designed as to permit them to properlyapply the rolling and pressing accessories to the parts being acted on. The fittings or fixtures on the jaw supporting members are so standardized and made uniform as to accommodate the diversified types of attachments or appliances which are to be mounted on the members for appropriately engaging the different curvatures of work. The interchangeability and standardized features are important.

Then too, the bodily adjustable toggles mounted on the intermediate portions of the long arms of the jaw supporting members 9 and 10 is a noticeable improvement, particularly when taken into conjunction with the independent adjustment of the toggling rendered possible through the doubleacting screw and feed block connection with the links of the toggle structure.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention- 1 after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.

1 claim:

1. In a repair tool of the class described, a pair of substantially duplicated L-shaped jaw supporting members having inturned short arms disposed in close spaced relationship, a pivoting and connecting device coupling said ends together, expanding and contracting means for the members, said means including sleeves slidably carried on said members, means for securing the sleeves in longitudinally adjusted position, a shaft mounted slidably and rotatably in said connecting device and having operable connection with said expanding and contracting means, and work engaging appliances carried by the free end portion of the aw supporting members.

2. In a tool of the class described, av pair of complemental substantially L-shaped members having their short arm portions directed inwardly toward each other, a connecting device coupling said arms together, said device having a central guide opening, work engaging means mounted on the free end portions of the long arms of said members, sleeves adj ustably mounted on the intermediate portions of the long arms, means for securing the sleeves, in adjusted position on the members, a shaft having a smooth portion extending rotatably and slidably through the guide openings in said connecting device, the shaft being provided on one end with a handle and on the opposite end with a double feed screw, feed blocks mounted on the screw-threaded portions of the feed screws for opposite movement, and links pivotally connected with the blocks and also pivotally connected with said sleeves.

In testimony whereof I atfix my signature.
